Discrete I/O; Usb; Ethernet; Sd Memory Option - Mettler Toledo IND246 Guia De Instalacion

IND246 Terminal Installation Manual
The COM2 port is galvanically isolated for both RS-232 and RS-485, to provide
surge voltage protection.
The RS-485 connection can be used as an RS-422 transmit only when sending
continuous output to a scoreboard or remote display.

Discrete I/O

The discrete I/O interface option provides dry-contact relay outputs. The relay
contacts will switch up to 30 volts DC or 250 volts AC at 1A.
The inputs are switch selectable as either active (for simple pushbutton control) or
passive (for connection to devices that supply their own power for the inputs).

USB

The USB port provided is a hardware bridge acting as a virtual COM port, and is
used for conversion of serial data. The port is bidirectional and can be configured
for various functions such as demand output, continuous output, extended
continuous output, SICS host communications or ASCII command input (C, T, P,
Z).

Ethernet

The IND246 Ethernet option provides an RJ45 jack for connection to an Ethernet
network or host device. A TCP socket connection can be made to port 1701 to
transfer files or to exchange data with a PC. This port can also operate as a print
client to send data to a network printer.

SD Memory Option

An optional SD Memory card provides a medium on which to store files such as
Alibi memory, truck weights in the vehicle application, IDs in the counting
application and target weights in the checkweighing application.
Note: The SD card is required for vehicle weighing and alibi memory.
The SD memory can also be used to extract and save the configuration and
calibration settings of the terminal. These can then be restored to the terminal or
loaded to a different terminal. This feature can be used to clone the setup of one
terminal then transfer it to other units, which minimizes the chance of error in
setting up a new configuration.
